- Some disposable pant-like undergarments manufactured today resemble regular cloth underwear in thalthey have a waist opening and a pair of leg openings. Such disposable pant-like undergarments can be pulled up around the torso of a user in a similar fashion as regular cloth underwear. It has been found that a disposable, absorbent pant-like undergarment is generally more discreet than a refastenable undergarment because it does not contain the extra material forming the hook or adhesive fasteners and loop or adhesive landing zone materials. A disposable pant-like undergarment tends to be sleeker, smoother and slimmer especially around the waist opening. For this reason, many adults suffering from incontinence tend to prefer the pantlike design.

- the ability of the front and back panels, 12 and 22 respectively, to contract will provide a restrictive force during use of the disposable pant-like undergarment 10 to ensure that it snugly conforms to the anatomy of the wearer's torso.
- the front and back panels, 12 and 22 respectively are constructed from a stretch bonded laminate (SBL) where the elastic core or middle layer 34 is elongated before the two outer nonwoven layers 32 and 36 are attached.
- the attachment can be by an adhesive, by heat, by pressure, by a combination of heat and pressure, etc.
- NBL necked bonded laminate
- the NBL material is also a three-layer laminate but the elastic core or middle layer 34 is not pre-stretched prior to being attached to the two outer nonwoven layers 32 and 36.
- the outer layers 32 and 36 are necked stretched before the elastic core or middle layer 34 is attached to them.
- the front and back panels, 12 and 22 respectively can be constructed from an elastic film that is capable of being stretched in at least one direction and desirably in both the machine direction and the cross-direction.
- the front and back panels, 12 and 22 respectively can be an elastic nonwoven that has a machine direction stretch or a cross-direction stretch. Extensible materials can also be used to form the front and back panels, 12 and 22 respectively, of the disposable pant-like undergarment 10.
- the front and back panels, 12 and 22 respectively can be formed from two outer layers 32 and 36 with a plurality of elastic strands sandwiched therebetween.

- the elastic strands can be aligned approximately parallel to one another or be angled or skewed relative to one another.
- the elastic strands can also be uniformly or randomly spaced apart from one another.
- the elastic strands can vary in shape, size, configuration, and/or length.
- the diameter and/or cross- sectional configuration of the elastic strands, the decitex (weight in grams per 10,000 meters of a strand) of the elastic strands, and the tension imparted into the elastic strands can all be varied to suit one's particular product needs.
- the elastic strands can have a round, semi-circular, square, rectangular, oval or some other geometrical configuration.
- the elastic strands can overlap, intersect or crisscross at least one other elastic strand.
- the various ways of positioning, orienting, and adhering the elastic strands to the two outer layers 32 and 36 are well known to those skilled in the art.
- the disposable pant-like undergarment 10 also includes an absorbent assembly 38.
- the absorbent assembly 38 includes a liquid pervious bodyside liner 40, a liquid-impervious outer cover 42, and an absorbent 44 positioned therebetween.
- a surge layer 46 can be optionally used, which is located between the bodyside liner 40 and the absorbent 44.
- the surge layer 46 can function to rapidly acquire and temporarily retain body fluid, such as urine, before it can be absorbed into the absorbent 44.
- the surge layer 46 is also capable of wicking the body fluid lengthwise and/or widthwise across its surface as well as directing the body fluid downward in a z direction toward the absorbent 44.
- the absorbent assembly 38 has a first end 48, a second end 50, a first side edge 52 and a second side edge 54.
- the absorbent assembly 38 is secured to the outer surface 16 of the front panel 12 approximate the first end 48 by an attachment 56 and is secured to the outer surface 26 of the back panel 22 approximate the second end 50 by an attachment 58.
- the absorbent assembly 38 is secured to the front and back panels, 12 and 22 respectively, after each panel has been stretched a predetermined amount.
- the absorbent assembly 38 By attaching the absorbent assembly 38 to the outer surfaces 16 and 26 of the front and back panels, 12 and 22 respectively, the absorbent assembly 38 is capable of expanding outward away from the user's torso while the front and back panels, 12 and 22 respectively, maintain their snug position against the user's torso. This unique ability for the absorbent assembly 38 to freely expand outward away from the user's torso without restrictions from the elastic front and back panels, 12 and 22 respectively, produces a more functional undergarment.
- the absorbent assembly 38 is capable of taking in and retaining additional body fluid as it expands outward, more so than if it was restricted by being secured to the inside surfaces 14 and 24 of the front and back panels, 12 and 22 respectively.
- the attachments 56 and 58 can be by various means and can include permanent attachments as well as removable or releasable attachments. Desirably, the attachments 56 and 58 are permanent attachments where they are not designed to be removed without destroying the bond.
- the attachments 56 and 58 can be formed by using glue, adhesive, ultrasonic bonds, heat bonds, pressure bonds, heat and pressure bonds, etc.
- the attachments 56 and 58 can also include a mechanical fastener, such as by sewing with thread, using buttons and button holes, using snaps, by employing hook and loop fasteners, etc.
- a hook and loop fastener is generally considered a releasable attachment.
- VELCRO® One type of hook and loop fastener is VELCRO® wherein a hook material is releasably engaged into a loop material.
- VELCRO® is a registered trademark of Velcro USA, Inc. having an office at 406 Brown Avenue, Manchester, New Hampshire 03103.
- the attachments 56 and 58 can be formed along a continuous line or over a surface area having a predetermined length and width.
- the attachments 56 and 58 can consist of intermittent point bonds that are spaced apart from one another.
- the intermittent point bonds can be formed by using a hot or cold melt adhesive or by forming ultrasonic bonds.
- Various bond formations can be used which are known to those skilled in the art.
- the attachments 56 and 58 are formed using intermittent bonds because it allows the elastic material forming the front and back panels, 12 and 22 respectively, to gather the absorbent assembly 38 as the elastic contracts.
- This gathering feature causes the absorbent assembly 38 to move outward away from the user's body prior to being insulted with body fluid.
- the front and back panels, 12 and 22 respectively can be stretched in a direction approximately parallel to the transverse axis Y--Y, or in any other direction or directions, before the absorbent assembly 38 is secured to it.
- the amount of stretch can vary.
- the front and back panels, 12 and 22 respectively can be stretched at least about 15% from a relaxed state before the absorbent assembly 38 is secured thereto.
- the front and back panels, 12 and 22 respectively can be stretched at least about 25% from a relaxed state before the absorbent assembly 38 is secured thereto. More desirably, the front and back panels, 12 and 22 respectively, can be stretched at least about 50% from a relaxed state before the absorbent 'assembly 38 is secured thereto.
- the front and back panels, 12 and 22 respectively can be stretched from between about 55% to about 1 ,000% from a relaxed state before the absorbent assembly 38 is secured thereto.
- the front and back panels, 12 and 22 respectively extend laterally beyond the first and second side edges 52 and 54 of the absorbent assembly 38.
- the front panel 12 also extends longitudinally beyond the first end 48 of the absorbent assembly 38 and the back panel 22 extends longitudinally beyond the second end 50 of the absorbent assembly 38. This lateral and longitudinal extension allows the front and back panels, 12 and 22 respectively, to elastically conform to the body of the wearer. Referring now to Figs. 2 and 5, when the absorbent assembly 38 is secured to the front and back panels, 12 and 22 respectively, a crotch region 60 is formed.
- the crotch region 60 separates the front panel 12 from the back panel 22 and is designed to cover the perineum area of the wearer.
- the crotch region 60 can cover a distance of a few inches in an infant diaper to several inches in an adult incontinence garment.
- a crotch region 60 in an infant diaper may range from about 2 inches (about 5 centimeters(cm)) to about 10 inches (about 25 cm).
- the crotch region 60 may range from about 6 inches (about15 cm) to about 20 inches (about 51 cm).
- Fig. 2 one can clearly sees that the bodyside liner 40 of the absorbent assembly 38 is partially overlapped by both the front panel 12 and the back panel 22. This overlap establishes a physical barrier between a portion of the bodyside liner 40 and the user's skin.
- the material of the front and back panels, 12 and 22 respectively, that overlap the bodyside liner 40 does not have to be permanently secured in place to the absorbent assembly 38 but does serve as an extra barrier layer to prevent rewet.
- "Rewet" is a condition where as the absorbent assembly 38 is compressed by movement of the user, for example by having the user sit down, body fluid retained by the absorbent 44 may be forced back towards the bodyside liner 40. As the body fluid contacts the bodyside liner 40, the user can experience a wet uncomfortable feeling. By having less of the bodyside liner 40 in direct contact with the user's skin, the user is less likely to experience this wet feeling.
- the portions of the front and back panels, 12 and 22 respectively, which overlap the bodyside liner 40 can vary from between about 10% to about 50% of the surface area of the bodyside liner 40. Desirably, the front and back panels, 12 and 22 respectively, will overlap at least about 15% of the bodyside liner 40. More desirably, the front and back panels, 12 and 22 respectively, will overlap at least about 20% of the bodyside liner 40. Most desirably, the front and back panels, 12 and 22 respectively, will overlap at least about 25% of the bodyside liner 40.
- the absorbent assembly 38 can be stretchable or non-stretchable in relation to the front and back panels, 12 and 22 respectively. Desirably, the absorbent assembly 38 is non-stretchable in relation to the front and back panels, 12 and 22 respectively. By having the absorbent assembly 38 be non-stretchable in relation to the front and back panels, 12 and 22 respectively, it is meant that the absorbent assembly 38 will not stretch appreciably in the longitudinal or transverse directions. The reason for this is that the front and back panels, 12 and 22 respectively, are elastically stretchable and can contract to snugly conform to the user's anatomy, especially to his or her torso.
- the absorbent assembly 38 could be constructed with a pleated or folded construction, so as to be capable of being expanded in the longitudinal or transverse directions, if expansion of the absorbent assembly is needed.
- the pleating or folding should occur before the absorbent assembly 38 is secured to the front and back panels, 12 and 22 respectively.
- the absorbent assembly 38 can be constructed and attached to the front and back panels, 12 and 22 respectively, in a way that will allow the absorbent assembly 38 to be gathered as the front and back panels, 12 and 22 respectively, elastically contract in the transverse direction. In either circumstance, the absorbent assembly 38 should remain over the perineum.
- the absorbent assembly 38 As the absorbent assembly 38 receives body fluid and/or excrement discharged by the wearer, it will be displaced outward, away from the user's torso.
- the ability of the absorbent assembly 38 to move outward away from the user's torso as additional body fluid is absorbed and retained is a direct result of the fact that it is secured to the outer surfaces 16 and 26 of the front and back panels, 12 and 22 respectively.
- the attachments 56 and 58 assure that the absorbent assembly 38 covers the perineum but is capable of moving outward away from the torso as additional body fluid is received and retained.
- the disposable pant-like undergarment 10 also has at least one elastic member 62 positioned adjacent to and aligned approximately parallel to each of the first and second side edges 52 and 54 of the absorbent assembly 38.
- Each of the elastic members 62 is situated between the bodyside liner 40 and the outer cover 42.
- the elastic members 62 provide a gasket to hold the edges 52 and 54 of the absorbent assembly 38 against the user's body.
- Each of the elastic members 62 can be in the form of an elastic strand, ribbon or strip. Desirably, from about two to six elastic members 62 will be positioned adjacent to each of the side edges 52 and 54. In Figs. 2 and 5, two elastic members 62 are' shown positioned adjacent to each of the side edges 52 and 54.
- the elastic members 62 are shown as having a round cross-sectional configuration although various other geometrical configurations can be utilized.
- the elastic members 62 extend parallel to the longitudinal axis X--X and extend completely through the crotch region 60. Desirably, the ends of the elastic members 62 will be located within the front and back panels, 12 and 22 respectively.
- the absorbent assembly 38 is capable of being folded transversely, approximate the transverse axis Y--Y, to enable the first and second side edges 18 and 20 of the front panel 12 to align with the first and second side edges 28 and 30 of the back panel 22, respectively.
- a pair of seams 64 and 66 is then formed to join the front panel 12 to the back panel 22.
- the seam 64 secures the second side edge 20 of the front panel 12 to the second side edge 30 of the back panel 22 while the seam 66 secures the first side edge 18 of the front panel 12 to the first side edge 28 of the back panel 22.
- the pant-like undergarment 10 has a waist opening 68 and a pair of leg openings 70 and 72. Since the front and back panels, 12 and 22 respectively, are formed from a stretchable elastic material, the waist opening 68 and the pair of leg openings 70 and 72 can expand or contract in size to accommodate the anatomy of the user.
- the disposable pant-like absorbent undergarment 10 can also include one or more elastic strands of waist elastics 74 and 76 positioned in the front and back panels, 12 and 22 respectively, approximate the waist opening 68.
- waist elastics 74 and 76 are depicted in the drawings, although it should be understood that from 1 to about 25 elastic strands 74 and 76 could be used, if desired.
- the elastic strands 74 and 76 can be positioned between the first and second layers, 32 and 34 respectively, as shown. Alternatively, the elastic strands 74 and 76 can be positioned between the second and third layers, 34 and 36 respectively, if desired.
- the elastic strands 74 and 76 are aligned approximately parallel to the transverse axis Y-Y and extend across each of the front and back panels, 12 and 22 respectively.
- the elastic strands 74 and 76 can be uniformly or randomly spaced apart from one another and are normally located within about 2 inches (about 5.4 cm) of the waist opening 68.
- the disposable pant-like absorbent undergarment 10 can also include one or more elastic strands of leg elastics 78 and 80 positioned in the front and back panels, 12 and 22 respectively, approximate the leg openings 70 and 72.
- Three elastic strands 78 and 80 are depicted in the drawings, although it should be understood that from 1 to about 10 elastic strands 78 and 80 could be used, if desired.
- the elastic strands 78 and 80 can be positioned between the first and second layers, 32 and 34 respectively, as shown in Fig. 2. Alternatively, the elastic strands 78 and 80 can be positioned between the second and third layers, 34 and 36 respectively, if desired. Normally, the elastic strands 78 and 80 are aligned approximately parallel to the edges of the front and back panels, 12 and 22 respectively, that are situated adjacent to the absorbent assembly 38. The elastic strands 78 and 80 can be uniformly or randomly spaced apart from one another and are normally located within about 0.3 inches (about ⁇ .76 cm) of the leg opening 70 and 72.
